What $10,000 earns in a 5-year CD at today’s rates

The headline number

A $10,000 deposit in the average 5-year CD does not turn into a windfall. At 1.71% APY, it grows to about $10,884.75 over five years before tax, which means roughly $884.75 in gross interest. Using a 22% federal tax example, the ending balance falls to about $10,690.10, and if inflation stayed at 3.8% for five years, that money would have the spending power of about $8,871.46 in today’s dollars.

Where the best rates sit

The average is one thing, but the spread at the top is still wide. NerdWallet lists 5-year CDs at Bread Savings at 4.00% APY, Synchrony Bank at 3.75% APY, Marcus by Goldman Sachs at 3.80% APY, NASA Federal Credit Union at 4.18% APY, E*TRADE at 4.10% APY, and TAB Bank at 4.20% APY. At 4.00% APY, $10,000 grows to about $12,166.53 before tax, while 4.20% APY lifts it to about $12,283.97.

That spread matters because Bankrate’s 2026 forecast puts the expected five-year CD average at about 1.55% APY, with a high around 1.7% APY. The current 1.71% average is already near the top of that forecast band, which suggests savers who locked in better rates earlier may already be holding stronger deals than many can find now.

Why the Federal Reserve still matters

CD pricing still reflects the wider rate climate. The Federal Reserve kept its target range for the federal funds rate at 3.5% to 3.75% in its April 29, 2026 statement, and that helps explain why CD yields have stayed elevated compared with many recent years. CDs appeal because they lock in a fixed return for a set period, but that certainty comes with a trade-off: your money is tied up, and early withdrawal penalties can apply.

That lock-in cuts both ways. If rates fall, a CD protects the yield you secured. If a better offer appears later, or if you suddenly need the cash, the same five-year term can become a constraint rather than an advantage.

Inflation and taxes change the story

Inflation is the reality check that turns a nominal gain into a much smaller real one. The Bureau of Labor Statistics said consumer prices rose 3.8% over the 12 months ending in April 2026, which is well above the average 5-year CD yield. At that pace, an average-rate CD barely preserves purchasing power before taxes, let alone after them.

A top-tier CD helps, but the margin is still thin once tax is added. Using the same 22% federal tax example, a 4.00% APY CD leaves about $11,689.89 after tax, which works out to roughly $9,701.16 in today’s dollars if inflation stayed at 3.8% for five years. Even 4.20% APY only gets you to about $11,781.49 after tax, or roughly $9,777.18 in real terms under the same inflation assumption.

That is the core problem for long-term savers: the headline APY can look respectable while the after-tax, inflation-adjusted result still trails the original $10,000. Under the same 22% tax example, you would need roughly 4.78% APY to simply keep pace with 3.8% inflation over five years, a level above the best quoted 5-year offers in this market.

The hidden cost of locking up cash

Opportunity cost is not just about missing a slightly better CD. It is also about losing flexibility while your money sits in one place for five years. Compared with the average 1.71% APY CD, a 4.00% APY account leaves about $999.79 more after tax over five years, and a 4.20% APY account leaves about $1,091.39 more after tax. That is a meaningful gap for the same $10,000 balance, and it shows why shopping the rate matters as much as choosing the term.

Still, safety is part of the appeal. FDIC deposit insurance covers up to $250,000 per depositor, per FDIC-insured bank, for each account ownership category, and the FDIC’s EDIE tool can help consumers check what portion of their deposits is insured. For money that must stay safe and predictable, that protection gives a CD a role, even if the real return is modest.

Bottom line

A 5-year CD is no longer a simple savings move, it is a trade-off between certainty and real return. The average account does little more than hold the line on paper, the best offers can still improve the math, and the combination of taxes plus 3.8% inflation means even a strong-looking APY may not deliver much spending power at maturity. For cash that cannot risk market losses, a CD can still fit, but in the current rate environment it is often a preservation tool first and a growth tool second.
